The analysis of the mgii double emissions near 2800 oa observed in the binary system βgem

الملخص EN

The paper aims to analyse the spectroscopic observations of the binary system β Gem in the ultraviolet region which obtained by IUE satellite and measured the MgII(h+k) emission line shape parameters, and applied the method of the nonradiative heating of stellar chromospheres by measuring the net radiative losses in the MgII(h+k).

The absorption and emission lines which found in the spectrograms of the binary system β Gem in the rang (2950 – 3150) oA had been identifier also.
